The Cash Conversion Cycle (CCC) is the number of days from when a business pays for inputs to when it collects cash from customers — calculated as DIO + DSO - DPO. A shorter CCC means less working capital is tied up in operations; a longer CCC drives working-capital financing needs.
The Cash Conversion Cycle measures the operational cash flow timing of a business: how long cash is tied up between paying for inputs (inventory, labor) and receiving payment from customers. Formula: CCC = Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) - Days Payable Outstanding (DPO). A business with DIO of 30 days, DSO of 45 days, and DPO of 20 days has a CCC of 55 days — meaning it takes 55 days from spending cash to recovering it. Each dollar of input is tied up for 55 days, which means the business needs working capital equivalent to roughly 55/365 × annual revenue to fund its operating cycle without external financing. Fast-payment B2C businesses (restaurants, retail) often have CCCs near zero or negative — they collect cash before they pay suppliers. B2B service businesses and distributors typically have CCCs of 30–90 days. Construction and manufacturing can run 90–180 days. A longer CCC directly translates into working-capital financing need — which is why industries with long CCCs are disproportionate users of lines of credit, invoice financing, and MCAs. The Federal Reserve's Small Business Credit Survey (https://www.fedsmallbusiness.org/survey/2024/report-on-employer-firms) documents how cash flow timing (the CCC) drives working capital financing demand across small business sectors. The Census Bureau's Quarterly Survey of Plant Capacity Utilization (https://www.census.gov/programs-surveys/qpc.html) provides manufacturing-sector data relevant to inventory cycle and CCC benchmarking.
Three levers: (1) Reduce DIO — tighten inventory management, just-in-time ordering. (2) Reduce DSO — invoice faster, follow up on AR sooner, offer early-pay discounts. (3) Increase DPO — negotiate longer payment terms with suppliers. Reducing CCC by 10 days on $3M revenue frees up roughly $82K in working capital.
A negative CCC means the business collects cash before it has to pay suppliers — effectively using supplier credit to fund operations. This is the position of most restaurants, some retailers, and fast-growing subscription businesses. Negative CCC businesses generate cash from growth rather than consuming it.
